Possible Causes
Leaky door gasket causing warm air infiltration, Misplaced or faulty temperature sensor, Control board not recognizing setpoint, Heavy frost restricting airflow
How to Fix / Troubleshooting
Safety first: Unplug the freezer before adjusting internal components.
- Inspect door gasket: Look for gaps, tears, or hardened sections. Close the door on a sheet of paper; if it pulls out easily, the seal is weak. Replace the gasket if needed.
- Check sensor placement: Ensure the cabinet temperature sensor is properly mounted and not touching the evaporator or walls directly, which can mislead the control.
- Defrost if frosted: If you see frost on the rear panel or shelves, fully defrost the unit to restore airflow.
- Verify temperature: Use a thermometer to confirm the actual temperature. If it is below -20°C (-4°F) and the unit still runs, the control may be faulty.
- Replace control components: Replace the temperature sensor first. If continuous running persists, the main control board or thermostat may need replacement.
Continuous running increases energy use and wear; if basic checks do not resolve it, seek professional service.
